Sesame Seeds Roasting Machine Easy to operate. Microwave power Sesame Seeds Roasting Machine and the conveyor speed can be sleepless adjustment, there is no thermal inertia, can open and stop at an time, easy to control,improve the production environment.Microwave equipment Full automatic crude soybean oil refinery plant with low consumption, no waste heat radiation, no dust, no noise, no pollution, easy to implement the testing standards of food hygiene.Sesame Seeds Roasting Machine Low-temperature sterilization, less loss of nutrients.Retain vitamin C,conventional heating treatment for fruits and vegetables is 46% ~ 50%, but the microwave Full automatic crude soybean oil refinery plant with low consumption can reach 60%~90%.Retain vitamin A,conventional heating treatment is 58%,but Shandong Leader Machinery Co.,ltd. the microwave can reach 84%,and does not affect the original flavor, is a good method for deep processing of fruits&vegetables and get green foods.

After heating, oil is then carried out with caustic soda to saponify the fatty acids and to ease the removal of the precipitate in centrifugal separator. The contact is made in mixer, and then a short contacting time is allowed in reactor. The lye saponifies the fatty acids in the oil and forms soap stock, which is removed together with the gums and the excess caustic solution. The caustic soda solution is coming from the caustic dosing device. The neutralized oil still contains small amounts of residual soap, which must be minimized before further processing. Some soft hot water (usually boiler treated water or steam condensates) is added to the oil in mixer and is then sent to washing centrifugal separator, where the residual soap is separated from the oil. The oil is dried under vacuum as the residual moisture must be reduced. The oil is first heated in a plate heat exchanger, by means of low pressure steam. The oil is then dried under vacuum in the dryer. of the bleaching section with its vacuum group. Then the oil is sent to the bleaching section by pump.

2)Bleaching section

Crude oil is fed to the oil-earth mixer through heat exchanger and heater. Prior to bleaching, the bleaching earth is dosed into the oil by means of a volumetric dosing system. The bleaching earth hopper is installed above the oil-earth mixer and assures continuous operation of the plant. The hopper can be automatically filled by means of the pneumatic earth feed assembly. After bleaching earth dosing, the oil flows into the bleacher. After bleaching, the oil-earth mixture is sent to filter and security filter by means of pump. After the filtration operation, oil recovery from spent cake is done by steam blowing and the spent cake is discharged and evacuated through a chute to a disposal container.

3)Deodorization Section

The bleached oil is first de-aerated in a buffer tank, It works at the same vacuum as the deodorizer and acts also as buffer feed capacity. After deaerator, Oil is sent by pump to be preheated by the heat exchange with the deodorized oil to a temperature between 190Â° and 210Â°C, and deodorized oil is cooling to a temperature of about 135Â°C. Finally, the oil is heated by conduction oil or high pressure steam until it reaches the final deodorizing temperature. After deodorization, the oil is cooled with feeding oil, polished, and pumped into storage tank.This cooling and contact combined with a lower velocity will allow catching nearly all fatty acids distillates present in the gas flow.

4)Crystallization Section

Feedstock is heated and pumped to crystallizers. The oil is cooled according to a pre-determined cooling profile by means of controlling the temperature of the cooling medium circulating in the cooling coils. The design of this cooling profile depends on the quality of feedstock and the quality of olein/stearin fractions required. This is to keep the oil homogenized with frequency mechanical agitation in the crystallizers. A typical cooling program lasts for a certain time, depending on the quality of feedstock and product. When the oil appears as a thick semi-solid mass (slurry) containing stearin crystals in liquid olein, it is ready for filtration. If the crystallization result is not desirable, the slurry can be circulated through the feed oil heater for re-heating before being sent back to the feed oil tank for re-processing.

5) Filtration Section

When crystallization is completed, the slurry is fed to the Membrane Filter Press for filtration. The operation includes filter feed, filtering, squeezing and cake releasing. When the chambers are full after cake forming, the pumping will stop and the membranes are inflated to squeeze dry the filter cakes. After which, the residual oil in the core is blown dry by compressed air. Thereafter, the filter is opened and the cake will drop into a stearin tank. The stearin cake is melted in this tank by steam coils before it is discharged to storage. Olein flows into the olein tank, and is pumped to the outer olein storage tank.
